The Short Version
If you're in a hurry, here's the cheat sheet:
Category Winners (Contractor Pricing)
- Lumber & Framing: Home Depot Pro (widest inventory + competitive pricing)
- Plumbing & Fixtures: Ferguson (trade pricing 20–35% below retail)
- Electrical: Lowe's ProServices (consistent lower pricing on wire and panels)
- Flooring & Tile: Lowe's (better selection at mid-range price points)
- Hardware & Fasteners: Home Depot (broader SKU range, frequent bulk deals)
- Appliances: Lowe's (better rebate programs for contractors)
But the real answer? It depends on your trade account status, location, and order size. Let's break it down.
Lumber & Framing
Why Home Depot Takes This Category
Home Depot has the largest lumber inventory of any big-box retailer, with 80% of stores carrying contractor-grade framing packages. Their Pro account pricing on dimensional lumber runs 5–8% below retail, and their delivery fleet is the most reliable for job-site drops.
Lowe's is competitive on SPF studs and sheet goods — often matching or beating Home Depot on individual SKUs during promotions. However, their framing lumber inventory is thinner in many markets, meaning you may need to wait for stock or settle for alternate species.
Ferguson doesn't compete seriously in framing lumber. They carry some specialty lumber (cedar, composite decking) but you won't build a framing package here.
| Lumber Item | Home Depot Pro | Lowe's Pro | Ferguson |
|---|---|---|---|
| 2x4x8 SPF Stud | $3.22 | $3.28 | — |
| 2x6x12 #2 | $8.97 | $9.14 | — |
| ¾" CDX Plywood | $42.98 | $41.48 | — |

Plumbing & Fixtures
Why Ferguson Dominates Plumbing
Ferguson is a trade-first supplier. Their showrooms exist to spec fixtures, and their trade pricing is 20–35% below retail on brands like Kohler, Moen, and Delta. For a bathroom rough-in package — supply lines, valves, fittings, drain assemblies — Ferguson's trade pricing regularly saves $200–$400 per bathroom compared to big-box stores.
Home Depot is fine for emergency plumbing supplies (PVC fittings, SharkBite connectors, basic faucets). Their retail pricing on fixtures is higher than Ferguson trade, but their Pro program narrows the gap on basic supplies.
Lowe's carries solid mid-range plumbing lines and occasionally has better promotional pricing on faucets. For a quick grab-and-go, Lowe's is adequate. For spec work? Ferguson every time.
If you don't have a Ferguson trade account, open one this week. For plumbing-heavy contractors, the savings on your first bathroom job will cover a year of better buying decisions. It's free and takes 15 minutes.

Lowe's Edges Out on Wire and Panels
Lowe's consistently prices Romex wire, breaker panels, and outlets 3–7% below Home Depot in most markets. Their private-label brands (Utilitech, for example) offer code-compliant alternatives at 15–20% below name brands — and for most residential electrical work, they're functionally identical.
Home Depot has a wider selection of specialty electrical (commercial panels, conduit, industrial-grade wire), which matters for commercial contractors. For residential electrical, Lowe's wins on price; for commercial, Home Depot wins on selection.
Ferguson carries some commercial electrical but it's not a core category. Skip them for electrical.
Flooring & Tile
Lowe's Owns the Mid-Range Flooring Game
For LVP (luxury vinyl plank), laminate, and ceramic tile in the $1.50–$4.00/sq ft range, Lowe's typically has better pricing and a more curated selection than Home Depot. Their installation partnerships also tend to be more competitive for contractor-installed projects.
Home Depot has the edge on budget flooring (sub-$1.50/sq ft options) and their LifeProof LVP line is genuinely good at its price point. For entry-level flooring on rental properties or spec homes, Home Depot is often cheapest.
Ferguson carries premium tile and stone (porcelain, natural stone) that neither big-box store stocks. If you're specifying $8+ per sq ft tile for high-end bathrooms, Ferguson or a dedicated tile showroom is where you'll find it — and their trade pricing makes it surprisingly competitive.
Hardware & Fasteners
Home Depot's SKU Depth Is Hard to Beat
For deck screws, drywall fasteners, Simpson connectors, hinges, pulls, and general hardware, Home Depot has the broadest selection and the most competitive bulk pricing. Their contractor packs (1 lb and 5 lb boxes) are consistently 10–15% cheaper per unit than buying individual packages.
Lowe's matches on common fasteners but has thinner inventory on specialty items (joist hangers, structural connectors, specialized anchors). If your hardware list is basic, Lowe's is fine. If you need anything unusual, Home Depot has it.
The Real Answer: Use All Three
The contractors saving the most money don't pick one supplier. They pick the right supplier for each category:
- Framing lumber and hardware? Home Depot Pro.
- Plumbing spec and fixtures? Ferguson trade account.
- Electrical and mid-range flooring? Lowe's ProServices.
Yes, this means managing three trade accounts and checking multiple sources. That's where the friction is — and that's exactly where the savings hide.
TruAries Sourcing lets you search materials across all three suppliers (and more) in a single query. No tab-switching. No calling reps. Just prices, side by side. The 60-second comparison that saves you $200+ per project.
What About 84 Lumber and Independents?
We focused on the big three, but don't sleep on 84 Lumber for volume framing orders (their unit pricing beats everyone when you're buying full loads) and your local independent suppliers for specialty items and relationship pricing.
Independent suppliers often can't compete on commodity items, but they beat big-box stores on service, delivery flexibility, and specialty products. For small-to-mid contractors, having one strong independent relationship alongside big-box trade accounts is the optimal setup.
Bottom Line
There's no single "cheapest" supplier. The cheapest option changes by category, by week, and by your account status. The only way to consistently pay less is to compare — and the contractors who compare on every order are the ones running the healthiest margins.
